DISH-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 489,190, dated January 3, 1893.

Application filed'N ovemher 11,1891. Serial No. 411,573, (No model.) v 1 I To all whom it? may concern:

Be it known that I, MONTGOMERY GROEN- ENDYKE, of Cieveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in DishWVashing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableotbers skilled in the art towhich it pertains to make and use the same.

Mydnvention relates to improvements in dish-washing machines; and it consists in certain features of construction and in combination of parts, hereinafter described,and pointed out in the claims, the object being to pro- 7 kinds, shapes and sizes, with greater facility and more thoroughly and effectually, than machines of this class heretofore devised, and without liability of breaking or mutilating the dishes; a machine that is exceedingly simple in construction, and comparatively noiseless in its operation.

In the accompanying drawings, Figure l is a front side elevation of my improved machine with the front side of the tank or easing removed. Fig. 2 isa view in perspective of an improved construction of dish-holding rack employed in my machine, and Figs. 3, 4,'and 5 are views in detail of the same. Fig. 6 is a perspective view of an improved paddle-wheel. I Fig. 7 is a detail in section hereinafter more fully described, and Fig. 8 is an enlarged perspectiveof a section of one of the paddles showing the transverse corrugations.

A represents the tank or casing of the ma chine. The front and rear sides of tank A affor bearing for a shaft, b, that is located preferably directly above the center inside the tank, as shown; and near the bottom, and preferably equidistant apart, the front-and rear walls of tank A have inwardly-projecting studs or lugs, a, that afford bearing for the respective ends of shafts c of the paddlewheels hereinafter described. Shafts b c, just inside the front wall of the tank, having rigidly mounted thereon, respectively,sprocketwheels, B 0, connected by an endlesschain, D, sprocket-wheel Bbeing quite large in diameteras compared with the size of sprocket-wheels C, shaft 1) extending out at either side of the machine, having a crank, b, at-

tached at the forward end for operating the (not shown) rigidly mounted thereon, at the rear end, to facilitate the operation.

The paddlewheels comprise paddles F mounted on diametrically opposite sides of shafts c, and the latter, midway paddles F, have mounted thereon similar paddles, G, there being preferably three paddles F to every pair of paddles G, the transverse edges g of paddles G being coincident, or approximately so, with the adjacent transverse edges fo'f paddles F. Paddles F G are made of she t metal and are secured to shafts to, (the body or central section of the latter being preferably square as shown)preferably by bending the lowerorsecuring end of the paddles flat with the surface of the shaftand riveting the end thus bent to the shaft, as at c. Paddles F G are corrugatedtransversely, as at f g, the corrugations increasing in depth toward the outer longitudinal edge of the paddles, and the paddles are substantially fan-shaped, flaring outward from the paddle-shafts, adjacent paddles on the same side of the shaft approximately making contact as atf g and thus forming substandles, but the relative size and arrangement space 9 between adjacent paddles G is located between two spaces f With such construcaforesaid by manipulatingcrank b, to revolve the paddle-wheelsthe water is agitated and thrown, from the grooves of the corrugations in the paddle wheels in numerous streams and projected against the dishes or articles to be washed with such force that they are thoroughly cleansed. i r

the dishes or articles to be washed, racks H paddle-wheels, and racks I-J being located at the sides of the paddle-wheels, and resting on the bottom A of tank A. These racks all comprise a rectangular frame of wire, the top V respective ends of the frame of elevated racks Hand the side and bottom membersyi i and jj', respectively, of the ends of the frame of lower racks I, J, at the same side of the ma and side members, h h, respectively, of the.

chine, being preferablyinte ral, that is, made machine, and having preferably a flywheel, 5 5

tially V-shaped spaces, f 9 between said padof paddles F G are substantially such that a tion, by operating the driving-mechanism H and I J represent racks for sup orting being located d1rectlyabove; the respective of a single piece of wire, and the ends' of the racks, at the top,- are connected by longitudinal wires, 70, respectively, members h h at either end of the upper racks being connected, at the bottom of said racks, by a cross-wire, Z. The sides and bottom of racks II, I, respectively, are substantially the same and comprise two lengths of sinuously-bent wire,

. N, at either side-of the rack, and suspended one above the other, for instance, from members h 2", respectively,- between the ends of the respective racks, and in a plane inclined toward the central portion of the bottom of the respective racks,-the sides of the respective folds of said said sinuously-bent wires being more or less inclined to each other, the

folds, at the ends, being arched, andat thelower end, reversely. curved, as shown at N','

the upper arched ends of the folds of lower members N being located approximately midmay .between the lower reversely-curved arched-ends of the adjacent upper members N. The construction of members N of racks H I ismore clearly shown in Fig. 3. Members N are held in the inclined position shown by means of reticulated wire-work, or netting,

I O, that is suspended from longitudinal wires It. With such construction racks H I are adapted to support almost any conceivable kind size and sha e of-dish cu s saucers 3 p 7 p 7 plates, creamerles, or what not,and are exce'edingly simple in construction and hence comparatively inexpensive. H

A somewhat modified, but exceedingly practical construction of members N, is shown in Fig. 4, where the upper ends of the folds are bent inward as at n End-racks J are adapted for supporting plates edgewise, longitudinal wires at the top and either side of these racks supporting parallel cross-wires p, and members j at the bottom and ends of the racks being centrally connected by longitudinal wires q, the latter being-in turn connected by transverse wires fl. Wiresrare bent upward, as at 'r, and wires p are bent laterally, as at p, to conform to the shape of plates, and a plate is thus effectually supported edgewise between a pair of wires r and a pair of wires 10.

Longitudinal wires 70 of racks H, have rigidly secured thereto, preferably by means of fine wire, n coiled around said longitudinal wires, upwardly and.outwardlydnclinedmem-.

'bers N substantially-the same in construction as members N, as shown more clearly in Fig. -5, and being more especially adapted for supporting goblets and the like.

To the ends and rear wall of tank A, are secured racks S forjsupporting knives, forks and the 1ike,'said racks, when in ahorizontal position, approximately covering the respectiveracks I J. Racks S, are like the upper portion of racks H they also have a member, at one or either side to support goblets, substantially like that shown fore referred to.

the paddles.

in Fig. 5 hereinbe-' Racks J do not make contact with the end walls of tank, A, but a sufficiently large interval is provided-between said racks and the end walls of the tank for receiving and supporting large platters, as at t.

Tank A is preferably mounted on a rim, as at 0, that is supported upon legs A suitable manner.

The bottom of tank A is preferably of a in any zigzag form in longitudinal section, beingpro- W vided', at the lowest points, (that are preferably directly under the paddle-wheels, and at the front side,) with drain-cocks a, whereby the tank can be rapidly drained.

Tank A at the upper end, all round, has an in wardly-projecting flange, as at aflprovided with numerous perforations, a and flange a has an upwardly-extending rim, as at a".

Cover or lid A of the tank has a depending longitudinally, as shown at A Fig. 7, that'- exhibits a transversesection of a portion of the sa|..c. 'By means. of such corrugations, the water as it is dashed against the under surface of the lid or cover, is redistributed about the tank, such corrugations directing the water in difierentdirections and greatly aiding in facilitating the work of the ma chine.

What I claim is:--

1. In a dish washing'machine, a tank, andme'ans for supporting dishes in combination with a paddle wheel having paddles provided with transverse corrugations which increase in depth from the shaft 2. In a dish washing machine, the combina-' tion with atank, of aplurality of racks provided with'dish receptacles arranged substantially as shown, a paddle wheel within each rack,'a main drivewheel and an endless belt engage ing the several paddle wheels and the drive wheel. 3. In a dish washing machine a-'tank,-a dish supporting rack, and an agitator crossing the tank transversely, in combination with a lid or cover for the tank provided with longitudi-' redistribute water dashedv nal corrugations to against itslower surface by the agitator.

In testimony whereof I sign this specifica- I ID to the outer edge of tion, in the presence of" two witnesses, this 29th day of October, 1891.
